Xinjiang enterprises successfully developed lithium ion battery which is not afraid of cold

To 40 ℃, 60 ℃ degrees centigrade below zero stable work of "the whole climate lithium battery" recently by researchers developed in xinjiang, the technology is expected to solve the lithium battery energy storage generally encountered low-temperature cannot charge problem, especially for winter cold northern regions like xinjiang is of great significance.

Ended on August 29th, "a guest in China" on the regional innovation entrepreneurship competition in xinjiang urumqi, "the whole climate lithium electricity pool "stand out from the many outstanding projects, won the division of urumqi and guest group of the first prize.

Developing the technology is a domestic enterprise to set up in June - xinjiang in new electric energy technology co., LTD., the core technology development, led by Dr Wang lei xinjiang institute of Chinese academy of sciences, has completed a variety of high and low temperature under the condition of product testing, is about to enter commercial product production phase.

The reporter understands, lithium battery is the electric car widely used as an electrochemical energy storage and power plant, compared to other battery has the advantages of high energy density, long cycle life. But it has poor low temperature performance, the electric car mileage by 40% - 40% in cold weather, sub-zero cannot charge, the electric motors as "flowers in the greenhouse.

To solve the problem in low temperature lithium-ion batteries, industry and academia have developed all sorts of technology, but the existing solution usually system complex, high cost, or damage to normal temperature and high temperature performance. Therefore the development of a low cost, the whole climate efficient lithium ion batteries for the development of electric vehicle industry plays an important role.

"Although the company set up time is not long, but before has focused on high and low temperature resistance of lithium ion battery and energy storage system development and solution of research and development, by providing high and low temperature resistance of lithium ion battery anode materials, can provide electric vehicles, unmanned aerial vehicles, robots, and other enterprises with high and low temperature resistant environment using solution." The company deputy general manager Mr Wong chiu said, "The whole climate lithium battery" in energy related products, information, transportation,special,special and other industries are widely used, has a broad market prospect.

Securities co., LTD., xinjiang urumqi division judges, large branch Dr. FuMing thinks, at present the country are developing new energy vehicles, and lithium ion battery energy storage technology, there are also many strong domestic enterprises in the lithium battery, xinjiang in the new electricity of new energy technology co., LTD. "the whole climate lithium battery" solitary characteristics in low temperature applications, with intellectual property rights, is located in the forefront in the industry. And northeast cold area, the technology for xinjiang and central Asia, Russia and other regions, has a broad application prospect.So the jury, think highly of the project, hoping to be held in September autonomous innovation entrepreneurship competition again to get good grades.

The reporter understands that the second "and Chinese" xinjiang innovation entrepreneurship competition finals will be held on September 19. On August 29, the regional setting of urumqi were selected enterprise group and a group of one third prize, a total of 12, along with excellent enterprise group before nine to into the finals. Project covers the 123 industrial and electrical business services, participating in the project have independent research and development, the new technology with strong generalization and a breakthrough tradition, the new concept of marketing.

The lithium battery

Lithium battery, is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution. With the development of science and technology, the lithium battery has now become the mainstream.

Lithium battery can be roughly divided into two categories: lithium battery and lithium ion batteries. Lithium ion battery does not contain lithium metal state, and can be recharged.

The fifth generation of rechargeable battery product lithium battery, which was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries. Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.
